Objective:To observe the effect and safety of the inhalation of Lanqin oral solutions combined with interferon in the treatment of children herpes angina. Methods:The children with herpes angina were randomly divided into two groups. On the basis of support treatment, the control group (57 cases) was intravenously treated with ribavirin, and the observation group (58 cases) was treated with the combined inhalation of interferon and Lanqin oral solutions. The time of transference cure, total efficiency and adverse drug reactions in the two groups were observed and compared. Results:The time of transference cure of the observation group was sig-nificantly shorter than that of the control group (P<0. 05) with higher total efficiency (P<0. 05). The adverse drug reactions were few and mild in the two groups. Conclusion:The inhalation of Lanqin oral solutions combined with interferon in the treatment of chil-dren with herpes angina is effective with short transference cure time, convenience of use and promising security, which is worthy of clinical application.

A novel chitosan derivant, N-octyl-N-arginine chitosan (OACS) with a mimetic structure of cell-penetrating peptides was synthesized by introducing hydrophilic arginine groups and hydrophobic octyl groups to the amino-group on chitosan's side chain. Structure of the obtained polymer was characterized by FT-IR and 1H NMR. The substitution degree of octyl and arginine groups was calculated through element analysis and spectrophotometric method, separately. The critical micelle concentration of OACS was 0.12 - 0.27 mgmL(-1) tested by fluorescence spectrometry. The solubility test showed OACS could easily dissolve in pH 1 - 12 solutions and self-assemble to form a micelle solution with light blue opalescence. The OACS micelles have a mean size of 158.4 - 224.6 nm, polydisperse index of 0.038 - 0.309 and a zeta potential of +19.16 - +30.80 mV determined by malvern zetasizer. AFM images confirmed free OACS micelle has a regular sphere form with a uniform particle size. MTT test confirmed that OACS was safe in 50 - 1 000 micromol-L(-1). The result of HepG2 cell experiment showed that the cell internalization of OACS micelles enhanced with increased substitution degree of arginine by 40 folds compared to chitosan. Thus, OACS micelles were a promising nano vehicle with permeation enhancement and drug carrier capability.

Objective To observe the apoptosis or oncosis of pancreatic acinar cells of different severity of acute pancreatitis (AP) and the release level of enzymes in vitro, and to investigate the relationship between them. Methods Two-step enzymatic digestion method was used to separate pancreatic acinar cells into 4 groups. 0. 1 μg/ml of the caerulein was added in the AP group. Caerulein and LPS (bacterial lipopolysaccharide, 10 mg/L) were added in LPS group. Caerulein and OCT (octreotide, 100 ng/ml) were added in OCT group. Medium was added in the control group. AO (acridine orange) and EB (ethidium bromide) double staining method was used to detect the incidence of apoptosis or oncosis of acinar cell. The release of intracellular enzyme was detected by measuring the concentrations of amylase and LDH in cell culture media by colorimetry method. Results The apoptosis index was 2.2 + 0.4, 6.4 ± 0.6, 4.6 + 0.4, 11.2 +1.2 in the control group, AP group, LPS group, OCT group; while the oncosis index was 3.0 +0.4, 17.2 ±1.6, 23.0 ± 2.2, 12.8 ± 1.4 in the control group, AP group, LPS group, OCT group; the release of LDH was (2180 ±240), (8060 ±930), (9460 +920), (6860 ±740) U/dl, the level of amylase was (1750 ± 190),(3820 ±460), (4420 ±480), (2260 ±260)U/L. All the values in the experiment groups were significantly higher than that in control group ( P ＜ 0.05 ). The oncosis index, LDH, amylase in LPS group was significantly higher than that in AP group ( P ＜ 0.05 ), but the apoptosis index in LPS group was significantly lower than that in AP group ( P ＜ 0.05 ). The apoptosis index in OCT group was significantly higher than that in AP group ( P ＜ 0. 05 ), but the oncosis index, LDH, amylase was significantly lower than that in AP group ( P ＜ 0. 05 ).Conclusions Induction of apoptosis and reduction of oncosis in AP pancreatic acinar cells can reduce the release of enzyme in acinar cells.

The results showed that patients with Cushing's syndrome had high prevalence of metabolic disorder and cardiovascular risk factors. Remission of diease and normalization of circulating cortisol level were not always followed by complete disappearance of metabolic disorder and cardiovascular risk factors.

Hepatectomy is the treatment of choice for huge ( ＞ 10 cm) hepatocellular carcinoma.However,the resection is more difficult and risky due to a huge space occupied by the tumor and vascular invasion.Precise hepatectomy is a new concept of liver surgery in the 21st century.The goal of which is the least invasive,most parenchymal preserving and optimal recovery.A male patient with a huge hepatocellular carcinoma (diameter =22.5 cm) received precise hepatectomy in the Department of Hepatobiliary Surgery of Fuzhou General Hospital of Nanjing Military Area.By using the digital medical technology and procedure of liver surgery planning system,the tumor and the whole structure of the liver were three dimensionally reconstructed,and the planning of resection was made.During surgery,the right liver artery and the right.porta hepatis were ligated and the right hemihepatic vessels were occluded.We accomplished right hepatectomy by accurate resection according the precisely planned preoperation,with less bleeding or no bleeding surgical field and rapid recovery.

A new HPLC-UV technique for the separation and analysis of 10 monosaccharides achieved within 13.5 min using 1-phenyl-3-methyl-5-pyrazolone (PMP) as the labelling molecule of the reductive monosaccharides has been established by combining common high performance liquid chromatography-UV and C18 column. The established technique was applied to the quantification of the monosaccharide components in extract of Silybum marianum. The results showed that the tested 10 monosaccharides as PMP derivatives were baseline separated under the HPLC conditions proposed. It was confirmed that Silybum marianum extract was composed of mannose, rhamnose, glucuronic acid, galacturonic acid, glucose, xylose, galactose and arabinose with the molar ratio of 0.66:0.84:0.58:1.0:1.6:0.69:2.7:4.8. Quantitative recoveries of the compositional monosaccharides separated from the extract were in the range of 92.4%-104.0%, and the RSD values fell within 0.68%-3.81%. The results demonstrated that the proposed HPLC method was simple, rapid, convenient, and precise, and it was applicable to the analysis of the compositional monosaccharides of Silybum marianum extract.
